猪圆环病毒2型(Porcine circovirus type 2,PCV2)已被确定为对全球养猪业最具经济破坏性的疾病之一。PCV2可导致仔猪断奶后多系统衰竭综合征(PMWS)、猪呼吸道疾病综合征(PRDC)、猪皮炎和肾炎综合征(PDNS)、生殖衰竭和腹泻。猪肺炎支原体...猪圆环病毒2型(Porcine circovirus type 2,PCV2)已被确定为对全球养猪业最具经济破坏性的疾病之一。PCV2可导致仔猪断奶后多系统衰竭综合征(PMWS)、猪呼吸道疾病综合征(PRDC)、猪皮炎和肾炎综合征(PDNS)、生殖衰竭和腹泻。猪肺炎支原体(Mycoplasma Hyopneumoniae,MHP)在猪群中很常见,具有高度传染性。猪支原体肺炎由MHP引起,其特征是持续性、无痰性咳嗽,发病率高,死亡率低。会降低日均体重增加并延迟上市日龄,导致全球养猪业遭受严重的经济损失。展开更多
